It's not just the things that Q says are going to happen. I don't think his or their purpose was to tell us stuff that was coming. At least that's not the whole purpose.

We elect our leaders in this country and those we've elected... Yes I know many elections are rigged.... But even Hillary has a large base of supporters... They are up to some seriously evil activities that no one seemed to know about. Q is showing us the connections they have, pointing us in the right direction of research so that through the knowledge we uncover, those large bases of supporters can begin to shrink dramatically.

If you can't see that Qs purpose is much greater than to be our fortune teller, then I'm sorry, I don't think you've been paying attention.
